Nitrogen-tracking tools for better crops and less pollution

As every gardner knows, nitrogen is crucial for a plant’s growth. But nitrogen absorption is inefficient. This means that on the scale of food crops, adding significant levels of nitrogen to the soil through fertilizer presents a number of problems, particularly river and groundwater pollution. As a result, finding a way to improve nitrogen uptake in agricultural products could improve yields and decrease risks to environmental and human health.
